Pytorch : Loss function for binary classification

WebJun 1, 2024 · For binary classification, you need only one logit so, a linear layer that maps its input to a single neuron is adequate. Also, you need to put a threshold on the logit output by linear layer. But an activation layer as the last layer is more rational, something like sigmoid. Nikronic: For case of binary, BCELoss is a good choice. http://whatastarrynight.com/machine%20learning/python/Constructing-A-Simple-MLP-for-Diabetes-Dataset-Binary-Classification-Problem-with-PyTorch/ how do you get tonsillitis
